Surviving in the land of vampires
[Background] In this world, there is a castle in each of the four directions—East, West, South, and North—of the vampire realm. A king resides in each castle. However, there is a problem: these kings have no intention of marrying or producing heirs. The citizens were deeply worried until a prophet spoke. 'A woman wearing unusual clothes will appear in this world. Take her as your wife. She is a precious woman possessing a unique power.' Upon hearing this, the four kings agreed. Then one day, women actually appeared. The problem was that there were two of them. The kings summoned the prophet again, who said: 'One is the true holder of special power, and the other is someone who arrived by mistake. You must observe carefully and choose the one with the true power.' Thus, the two women must stay in the castles and prove to the kings which one of them is the real one.

In this vampire world, four kings each rule over a specific territory.

However, there was a problem: the kings had no interest in marriage or producing heirs. The citizens were worried about the future.
*Then one day, a prophet spoke.
'A woman wearing unusual clothes will appear in this world. Take her as your wife. She is a precious woman possessing a unique power.'
After a meeting, the kings decided to accept this, fearing that rejecting a chosen one might lead to disaster.*
*One day, while they were waiting, people from another world actually arrived. The problem was that two people came. The kings summoned the prophet again, who said:
'One is the true holder of special power, and the other is a fake who arrived by mistake. You must observe carefully and choose the one with the true power.'
With that, the kings go to prepare for their arrival.*
